CHARLES E. ATHERTON, OF PATERSON, NEW JERSEY.

VAPOR-LAMP.

Specification of Letters Patent No. 30,556, dated November 6, 1860.

To all whom it may concern:

Be it known that 1, CHARLES E. ATHER- TON, of the city of Paterson,Passaic county, and State of New Jersey, have invented a gas-receiver tobe used upon portable selfgenerating gas -lamps and an improved methodof constructing and connecting the generating and burning tubes of suchlamps with the receiver.

The nature of my invention as respects the receiver, consists inaffixing to the generating tube of the lamp a gas chamber or receiver,and so connecting the generating tube, and burning tubes to suchreceiver, as to prevent any obstruction in the burning tubes fromcorrosion and filth, and an overflow of the burning fluid through theburners in case of sudden extinguishment of the flame, or neglect instopping the supply of fluid to the generatlng tube.

As respects the generating tube, it consists in letting the upper endthereof into the gas receiver, and providing the end of the tube so letinto the receiver with a selfregulating valve or gage, which working inthe receiver, by means of an expansion wire, and lever, compels the gasto enter into the receiver, before entering the burning tubes; and atthe same time regulating the flow of gas from the generating tube intothe receiver; and dispensing entirely with the wick, running through thegenerating tube for the purpose of regulating the supply of fluid in thegenerating tube, universal in all other gas burning lamps.

As respects the burning tubes, my invention consists in connecting themwith the gas-receiver instead of the generating tube, by means whereof,the gas is compelled, to pass through the receiver before entering them,and thus entirely preventing any overflow of the fluid through thesetubes, and out at the burners in case of sudden extinguishment of theflame or otherwise as above set forth; and also preventing anyobstruction of the opening of the burning tube from corrosion or filth.

The following is a full, clear and exact description and explanation ofthe principle, construction and operation of my said improvement,reference being had to the annexed drawings, making a part of thesespecifications.

Figure 1, represents a perspective view of the lamp with the gasreceiver and its connections attached thereto, viz. :Gr, elevatedreservoir, containing the fluid from which the gas is generated; F,feed-pipe, connecting with the generating tube; E, stop-cock, regulatingthe supply of fluid from the feedpipe F, into the generating tube; B,generating tube, with a valve or gage at the upper end permitting thegas to enter the receiver; A A gas receiver, aflixed to the upper end ofgenerating tube; C C, burning tubes connecting with the receiver; D D,burners.

Fig. 2, represents a sectional view of the gas receiver, generating andburning tubes, as arranged for two burners, and their connections B B,top of gas receiver, A A; d d, springs pressing upon the shoulder of thevalve or gage at the top of the generating tube; (2 e c valve or gage, ii, shoulder of valve a a, expansion wire resting against lever Z), Z),lever; c, beveled lifting pin attached to one end of lever b, andworking into the horizontal hole 9 of valves 6 e e; h 71,, openings ofburning tubes 71 i; A A, gas receiver; is, generating tube; D D,burners.

Fig. 3 represents gas receiver, generating and burning tubes, asarranged for one burner, and their connections; A A receiver; B, top ofreceiver; 7 f, spiral spring resting upon shoulder of valve a a; b b I)expansion wire, with beveled end working into horizontal hole 9 of valvea a; h opening of burning tube z"; D, burner; K generating tube.

Fig. 4 represents plan of the interior arrangement of receiver, asarranged for two burners; a a expansion wire resting against one end oflever b; 71, fulcrum or lever b, c beveled lifting-pin working into thehorizontal hole 9, of valve 6 e.

Fig. 5 represents spring (Z d on the under side of the top of receiver,and resting upon the shoulder of valve 6 c e, as seen in Fig. 2.

Fig. 6 represents plan of the interior arrangement of the receiver, asarranged for one burner; b b 6, expansion wire with beveled end workinginto horizontal hole 9 of valve or a, as seen in Fig. 3.

Fig. 7 represents spiral spring 0 resting upon shoulder of valve a a, asseen in Fig. 3; 6 represents shoulder of valve (4' a, also seen in Fig.3.

The heat from the flame, acting upon the receiver A A made of cast iron,causes the wire a a, made of soft brass to expand, which acting upon oneend of lever b, forces the beveled end of the lifting pin 0, into thehorizontal hole 9, of the valve or gage e c e,

thereby raising the Valve and admitting the gas generated in the'tube K(F ig. 2) into the receiver A A and from thence through the burningtubes i Fig. 2) to the burners.

The contraction of the Wire a a, by the extinguishment of the flame andthe spring cl cl (Fig. 2) pressing upon the shoulder of valve 6 e 6(Fig. 2), shuts it, and prevents either the gas or fluid from escapingfrom the generating tube K (Fig. 2) into the receiver; and also preventsany overflow of fluid through the burning tubes 2' 2' (Fig. 2) as occursin all other methods of connection;

" and also prevents any obstruction of the burning tubes 2' i (Fig. 2),caused by the action of the fluid upon the metal of the burning tubes,or by the collection of filth.

I do not claim as my invention the generating tube nor the burningtubes; nor

the burners; nor the expansion rod; nor the elevated reservoir; nor thefeed pipe, and stop cock regulating the supply of fluid; but

What I do claim as my invention or improvement and desire to secure byLetters Patent, is

l. The combination and arrangement 01": the gas receiver, theself-acting valve, -or gage, at the top of the generating tube, with theuse of the metal rod, and beveled pin, substantially as and for thepurpose set forth.

2. The peculiar connection of the burning" tubes with the receiver forthe purpose set forth.
